Title:
KEY STRUCTURE AND KEY MODULE CAPABLE OF REDUCING NOISE DURING KEY PRESSING
Document Type and Number:
WIPO Patent Application WO/2020/010481
Kind Code:
A1
Abstract:
Disclosed are a key structure and key module capable of reducing noise during key pressing. The key structure comprises a circuit board, a Dome fixing film, a Dome and a gasket, wherein the circuit board is provided with a conducting circuit; a key part of the conducting circuit comprises a first conducting electrode and a second conducting electrode; a first insulating portion is provided between the first conducting electrode and the second conducting electrode; the Dome is arranged corresponding to the key part on the conducting circuit; the Dome fixing film is provided above the Dome; and the gasket made of a flexible buffering conducting material is provided between the Dome and the circuit board. According to the present invention, a gasket made of a flexible buffering conducting material is provided between a circuit board and a Dome, and the force generated by a collision between the Dome and the circuit board when the Dome is pressed can be buffered by means of the gasket, thereby reducing a key pressing sound of a thin-film key and improving the quality of the final product as a whole.
